Humans don't always behave in their own best interests, and that includes the way we walk. Or don't.

A recent survey showed that most people — 94% of those surveyed nationwide — know that walking is good for their health. And nearly as many said it was a good way to lose weight and prevent heart disease. Eight-seven percent said walking is a good way to reduce anxiety, and about 80% said it helps depression.

But 79% said they should walk more than they do, and 35% said they are walking less than they did five years ago. A third of the people surveyed said they don't walk for 10 minutes at one time over the course of a week.
